As we now have an enum Operator that comes with many useful helper methods switching to use
that instead of the enums defined separately. Also switches to using the new enum's helper
methods where applicable removing duplicate parsing logic.
This breaks backwards compatibility. Documenting the break in

There was only a single actual "use" of close, for a threadlocal
in VersionFieldMapper. However, that threadlocal is completely
unnecessary, so this change removes the threadlocal and
close() altogether.
This commit consolidates several abstractions on the shard level in
ordinary classes not managed by the shard level guice injector.
Several classes have been collapsed into IndexShard and IndexShardGatewayService
was cleaned up to be more lightweight and self-contained. It has also been moved into
the index.shard package and it's operation is renamed from recovery from "gateway" to recovery
from "store" or "shard_store".
Closes#11847
This commit folds ShardRouting, ImmutableShardRouting and MutableShardRouting
into ShardRouting. All mutators are package private anyway today so it's just
unnecessary abstraction.
ShardRoutings are now frozen once they are added to the IndexRoutingTable
to prevent modifications outside of the allocation code.
This commit makes the get and search APIs always return `_parent`, `_routing`,
`_timestamp` and `_ttl` in addition to `_id` and `_type`. This way, consumers
always have all required information in order to reindex a document.
Currently the SnapshotsService is concerned with both maintaining the global snapshot lifecycle on the master node as well as responsible for keeping track of individual shards on the data nodes. This refactoring separates two areas of concerns by moving all shard-level operations into a separate SnapshotShardsService.

Refactors CommonTermsQuery analogous to TermQueryBuilder. Still left to do are
the tests to compare between builder and actual Lucene query.

This PR is against the query-refactoring branch.
This commit makes SimpleQueryStringBuilder streamable, add hashCode and equals. Adds a dedicated builder/parser unit test, fixes formatting, adds JavaDoc where needed, adjust the handling of default values according to https://github.com/elastic/dev/blob/master/design/queries/general-guidelines.md
Switched to using toLanguageTag/forLanguageTag when parsing Locales. Using LocaleUtils from either Elasticsearch or Apache commons resulted in Locales not passing the roundtrip test. For more info see https://issues.apache.org/jira/browse/LUCENE-4021

Since there is a recommended version of JDK, it would be helpful to provide a link to the Oracle documentation. Since there are many versions of Java, those that are new or infrequent users of Java would find the link helpful. Thanks!
Closes#11792
Currently the filter cache is configured to have a maximum size in bytes of 10%
of the JVM memory, and a maximum number of cached filters (across all segments
of all shard on the same node) of 100000. I would like to change the latter to
a more reasonable value of 1000.
Given that we track the most 256 most recently used filters per index and only
cache those that have been seen 5 times or more, a single index cannot have more
than 50 hot filters, so a maximum number of cached filters of 1000 per node
should be more than necessary.
Today, we have scheduled reroute that kicks every 10 seconds and checks if a
reroute is needed. We use it when adding nodes, since we don't reroute right
away once its added, and give it a time window to add additional nodes.
We do have recover after nodes setting and such in order to wait for enough
nodes to be added, and also, it really depends at what part of the 10s window
you end up, sometimes, it might not be effective at all. In general, its historic
from the times before we had recover after nodes and such.
This change removes the 10s scheduling, simplifies RoutingService, and adds
explicit reroute when a node is added to the system. It also adds unit tests
to RoutingService.
